Built in 1839, the Arsenal was designed by noted architect James Dakin and is associated with an infamous battle that happened after the Civil War. During the period of Reconstruction several clashes occurred throughout the state between integrated and white supremacist groups. In 1874, the Battle of Liberty Place, wherein the Metropolitan Police of New Orleans were pitted against the Crescent City White League, occurred. The White League prevailed, forcing the Metropolitan Police into the Customhouse and the Cabildo. From the adjacent Arsenal, the Police fought back by shooting cannonballs toward Chartres Street.
Today, the Arsenal offers exhibits and occasional recreational and educational events.
